There are 5 remaining rules from StyleCop Classic which are marked to be implemented but haven't been yet. I'm considering removing the [DiagnosticAnalyzer(LanguageNames.CSharp)] attribute from them and pushing them back to a 1.1 release. Removing the attribute hides them from the UI where they would otherwise be indistiguishable from rules which work but are disabled by default. I believe new rules SA1133 and SA1134 fit into this same category because I created placeholder classes for them already.
